This guy who looks a little scary at first is the Zanzibar red-backed Judean monkey, and the mountain ghost in ancient Chinese mythology is just this kind of appearance.
Located in the Indian Ocean in the east of Africa, Zanzibar is an integral part of Tanzania, covering an area of 2,654 square kilometers, consisting of more than 20 small islands, 36 kilometers away from the African continent, and a population of about 1.3 million.
It is precisely because Zanzibar is far from the mainland that the island is home to a number of unique species.
The red-backed colobus monkey is the flagship species of Mulberry Island, very rare, its front is white, the shoulders and arms are black, the back is full of bright red hair, and the fur is soft and shiny, so it is called the red-backed Judea monkey.
Zanzibar's colobus monkeys originally grew in Tanzania and Uganda in East Africa, but are now extinct on the African continent, with only about 1,500 colobus monkeys currently inhabiting the jungles of Zanzibar.
This species differs from other Judeo-monkeys in that they have long white hairs on their crowns, black faces, pink lips, and a distinctive white background under their noses.
Their fingers are particularly long, and the thumb has degenerated into a small wart, so it is called a colobus monkey, and the absence of a thumb is also the difference from the langur.
The Zanzibar Red Colobus Monkey is completely vegetarian and eats large amounts of leaves, fruits, mosses and seeds every day, up to 2-3 kg.
The complex structure of the stomach has adapted to digest leaves, not to eat meat, and only occasionally eat soil and charcoal to help digest toxins on the leaves.
Male Zanzibar red colobus monkeys are sexually mature at four years of age, giving birth to 1 litter per year, 1 litter per litter, and the gestation period is 5 months, and the pups are carried by the female in the tree.
Red-backed Monkeys are more arboreal, with 5-50 males per group, and males who have no chance to become leaders will leave the family group and mix with the world after adulthood. Although Zanzibar is a paradise for tourism, the forest is highly degraded, and the scarcity of food forms a social system of "fission integration" of the Monkey population.
